PUMP-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 790,187, dated May 16, 1905.

- Application filed June so, 1902. seial No. 113,858.

To all whom it may concern.-

Be it known that I, RUDOLPH CONRADER, a citizen of the United States, residing at Erie, in the county of Erie and State of Pennsyl- Vania, have invented new and useful Improve ments in Pump-Governors, of which the followingis a specification.

This invention relates to pump-governors;

and it consists in certain improvements in the construction thereof, as will be hereinafter fully described, and pointed out in the claims. The objects of the invention are to provide a pump-governor which may be actuated entirely by the fluids actuating and actuated by the pump. 1

Some features of the device may be utilized with other governing devices.

The objects of the invention, therefore,,-include in their broader scope not only those just hereinbefore stated, but also to provide the diflerent features of the mechanism herel in Fig. 1.

of the governor-lever mechanism on the line, 4 4 in Fig. 3. Fig. 5 shows a view, partly in section, of an alternative construction.

A marks the governor-valve chamber form-' ing part of the connections for the pump-ac-g tuating fluid; a, the usual diaphragm; B, the usual valve used on throttlinggovernors. The'cap C of the valve-chamber A forms a base for a frame, having the upright G.

The plate 0 connects the upright C, and extending above the uprights O and C is a frame C Arranged on the plate 0 is a governor-motor cylinder D. This communicates, through the connection E, With the dischargepassage leading from the pump. Arranged within the cylinder D, above the opening of the passage E to the cylinder D, is a piston F, and extending from this piston is a stem f. A spool f is secured to this stem f. An arm 0 extends from the frame C and forms a pivotal support for alever F. The lever F has aforked end and is rounded to operate between 'theshoulders ofthespoolf. Theo'ppositeend of the lever is similarly arranged to operate in the spool The spool f is screwed onto a short stem F and is locked in position thereon by ajam-nutf A screw-threaded sleeve f? is arranged on the stem f above the spool f This sleeve is provided with a hand-wheel f, so that it can be readily manipulated. Screwed onto the thread on the sleeve is a yoke f and extending from the arms of the yoke are the springs F The lower end of the springs are attached to the plate 0. It will readily be seen that by turning the sleeve f the tension of the springs F may be readily ad justed as desired. When adjusted, the yoke may be locked. in position by the jam-nutf. The pin F is of such length that it will contact the upper end of the stem 6 when the piston F is forced upwardly by the pressure exerted by the pump. 1 This part of the mechanism operates in the manner of ordinary regulators. The springs F are adjusted so as to exert a counter-pressure in the piston Fsufficiently to prevent a movement of the. piston F until the pressure exerted by the pumped fluid has reached its desired maximum. When the pressure does'reach this point, the piston F is forced upwardly, the pin F downwardly against the stem 6, and the valve closed, so as to completely stop the pump. The stem 6 is arranged to have a free downward movement with relation to the other connections of the governor, so as to permit this action of the regulator. The upper end of the stem has the shoulder 6 and a spring-b is tensioned between the shoulder b and the frame 0 and this immediately opens the valve when the pressure falls below the maximum and allows the lifting of the pin F. The spring 5 needs to be only of sufiicient tension to lift the valve and connecting parts.

Arranged in the cylinder D, beneath the piston F and connection E, is a second piston G. Extending from this piston is a stem and secured on this stem is a collar 9'. A pin extends through this collar and the stem and also through a lever H. The lever H has on its edges the guides h. The fulcrum-block I is arranged to slide on these guides. Extending from the fulcrum-blocks are the fulcrumpins These pins extend into a yoke J. The yoke J is arranged to slide in the guides c on the frame C. H are the rounded portions 70, which engage a spool L. An adjusting-nut b is threaded onto the valve-stem b and screwed into the spool L. Its lower end contacts a shoulder I)", fixed on the stem B. This adjusting-nut is locked in place by a jam-nut b. It will readily be seen by following through this mechanism that as the piston G is forced downwardly, carrying with it the stem 9, the collar g and the outer end of the lever H is also forced downwardly. This operating upon the fulcrum formed by the pin 2: raises the end of the lever at the valve-stem, and this permits the spring 6* to lift the valve and give to it a wider opening. Beneath the lever H and preferably surrounding the stem 9 is a spring G, which forms a counter-pressure mechanism against the motor formed by the piston G and cylinder D. The upper end of this spring rests against the collar g and the lower end against a collar The collar g is mounted on an adjusting-nut g screwed into the base-plate C. A jam-nut r locks the adjusting-nut g in place. The outer end of the lever H is provided with a weight H. By shifting this weight the amount of counter-pressure can also be varied. Secured to the yoke J by means of a swivel-joint 7:: is a screw K. This screw K passes through an extension 0 arranged on the frame C. It will readily be observed that the yoke J may be adjusted to any position by the screw K and locked in any position by the jam-nut This adjusting of the yoke J changes the position of the fulcrum e, and consequently changes the movement of the valve relatively to the movement of the motor-piston G. The operation of this feature of the device is as follows: As the pumppressure operating through the connecting medium increases it actuates the piston G, and this operating through the connecting mechanism, the stem 9, and lever H permits the valve B to be lifted by the spring I). When there is no pressure on the pumped fluid, the lever H simply rests on the spring Gr. Theoretically the sleeve 7) should then be adjusted so as to place the valve B just at the point of opening-that is, there being a zero-load on the pump the valve should be set at zero. In order to start the pump and overcome the friction of the parts, the valve B, with no pressure on the pumped fluid, should be sufficiently open to give to the pump the desired speed. As the pressure on the pumped fluid increases the pump may increase or decrease in speed, depending on whether the valve B is raised in proper proportion to the increase in the load. By turning the screw K, and thus adjusting the yoke J, the movement of the valve relative to the movement of the pressure device incident to the pumped On the inner end of the lever 1 1 uid-pressure may be varied, so that the valveopening will be proportioned exactly to the load. In adjusting the governor, therefore, it is simply necessary to start with a zero pumped fluid-pressure, set the valve by means of the sleeve 7/ to give the speed to the pump desired, then allow the pressure on the pumped fluid to run up, and then adjust theyoke so as to give a valve-opening that will bring the pump to the initial speed. It will be found that this adjustment of the yoke will give a proper valve-opening for all intermediate loads, as well as greater loads. Of course the adjustment of the valve, as just hereinbefore described, maybe accomplished by adjusting the collar g so as to raise or lower the spring (ir; but this involves the tilting of the lever ll, so that it is preferable to make the adj ustment by means of the sleeve 6'.

It will be noted that by securing the end of the lever H to the stem r the movement of the lever at the pointof connection is a straight line, while the movementof the partll of the lever is arranged with the fulcrum as a center. As the stem is moved, however, the lever H slides on the block 1, so as to vary the length of the lever between the fulcrum and the ends it. This action of the lever compensates for the varying arm incident to the oscillation of the lever If, so that a given movement of the stem 7 with the lever II in any position gives to the stem a proportionately similar movement.

It will of course be understood that the stem 6 instead of being connected directly to a throttle-valve may be connected to any of the well-known valve mechanisms (not of the throttle-valve type) and will operate in a manner substantially similar to one connected to a throttle-valve.

While a governor-motor connected with the discharge of the pump and subjected to the pumped fluid-pressure forms for many purposes a sufiiciently accurate governor, in some relations such a connection does not form a complete governing apparatus.

In pumping liquids the intake-pressure of course is exerted upon the piston and neutralizes the load upon the piston to the extent of the intake-pressure. \Vith gases the intakepressure increases or decreases the load on the pump, depending upon how closely such intake-pressure approximates the dischargepressure of the pump. It becomes necessary, therefore, to compensate for this disturbing influence, and in the accompanying drawings I have arranged the mechanism for compensating especially for liquids; but it may be utilized with gases where the intake and discharge pressure approximate each other. The lower end of the cylinder 1) is closed and a connection E made with the intake of the pump. As the piston presents practically the same area at both sides, the intake-pressure is exerted against the discharge-pressu re in the governor-motor and effects the governing influence of the discharge-pressure to just the extent that the intake-pressure neutralizes the load on the pump. Thus if the intake-pressure were equal to the discharge-pressure the effect, of the discharge-pressure on the piston G would practically be neutralized, as would the work of the pump. Another disturbing influence as to the uniformity of the speed of the pump is the variation in the actuatingfluid pressure,(ordinarily avariation in boilerpressure.) To compensate for this, I have arranged a mechanism as follows: Extending from the plate 0 is the arm G which sustains a cylinder M. is provided with a connection m, leading to some part of the actuating-fluid system. Arranged in this cylinder is the piston m, and resting on this piston is the extension g on the stem g. It will be noted that the stem or actuating fluid operating upon the piston m forms a part of the counter-pressure mechanism supporting the spring G, and so that as the actuating-fluid pressure increases the counter-pressure mechanism of the governor increases in force, so that a smaller opening is given to the valve for a given pumped fluid-v pressure. The higher actuating-fluid pressure, however, gives to the pump with this,

smaller valve-opening the same energy that would be given to it by an actuating fluid at less pressure and larger valve-opening.

In Fig. 5 I show an alternative construction comprising the broader features of my invention. In it A marks the valve-chamber, and B the valve. These are substantially similar to the sameparts in Fig. 1. Secured to the valve-chamber is an arm C, to which is secured a cylinder D. Leading to this cylinder is the connection E, which is similar to the connection E in Fig. 1. The piston Gr is arranged in said cylinder with a counter-pressure spring G arranged between the piston and the end of the cylinder. tending from the piston is a stem 9. This stem is connected by a link g with a bellcrank-lever H The bell-crank lever is pivoted on an arm G, extending from the chamber A. The valve-stem 6, extending from.

the valve B, is provided with a pin 6, which operates in a slot /t at the end of the bell-- The bell-crank lever is pro-- crank lever H vided with a series of holes if, any of which may be made the pivot of the lever H this means the length of the arm in which is arranged the slot 7L2. may be varied, so as to vary the movement of the valve with a given movement of the governor-motor.
